Description

The TPS77433 are low-dropout regulators with integrated power-on reset and power good (PG) function respectively. These devices are capable of supplying 250 mA of output current with a dropout of 200 mV (TPS77333, TPS77433). Quiescent current is 92 A at full load dropping down to 1 A when device is disabled. These TPS77433 are optimized to be stable with a wide range of output capacitors including low ESR ceramic (10 F) or low capacitance (1 F) tantalum capacitors. These devices have extremely low noise output performance (55 Vrms) without using any added filter capacitors. TPS77433 are designed to have fast transient response for larger load current changes.

The TPS77433  is offered in 1.5-V, 1.6 V (TPS77316 only), 1.8-V, 2.7-V, 2.8-V, 3.3-V, and 5.0-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.5 V to 5.5 V). Output voltage tolerance is 2% over line, load, and temperature ranges. The TPS77433 families are available in 8-pin MSOP (DGK) packages.(programmable over the range of 1.5 V to 5.5 V). Output voltage tolerance is 2% over line, load, and temperature ranges. The TPS773xx and TPS774xx families are available in 8-pin MSOP (DGK) packages.
